Henan Diteli Electric to Showcase New Energy & Storage Transformers at ES Energy Storage Expo 2025

Event Overview

Event: ES Energy Storage Expo
Date: November 18–20
Venue: New International Expo Center
Booth Number: Hall N3 · 3S08
Exhibitor: Henan Diteli Electric Co., Ltd.

The ES Energy Storage Expo is one of the most influential industry events focusing on new power systems, energy storage technologies, and renewable energy equipment.
It serves not only as a platform to display cutting-edge technologies but also as a key hub for upstream and downstream collaboration across the entire energy storage industry chain.

This year, Henan Diteli Electric will present its latest high-performance transformer solutions designed for new energy, energy storage, and photovoltaic power applications.

Featured Products at the Expo

1. New Energy Oil-Immersed Transformer

A transformer designed for wind power, photovoltaic power generation, and other renewable energy applications.
Key advantages include:

  • Lightweight structure

  • Lower cost and high reliability

  • Excellent thermal stability

  • Enhanced efficiency for long-term operation

The oil-immersed design improves heat dissipation and extends service life, making it a core component in new energy power systems.

2. Energy Storage Dry-Type Transformer

A safe, environmentally friendly dry-type transformer widely used in modern energy storage systems.

Key characteristics:

  • Oil-free structure

  • High safety and excellent insulation

  • No risk of leakage or fire

  • Air or solid insulation cooling

  • Compact design and easy maintenance

It is suitable for battery storage, supercapacitor systems, and various peak-shaving, frequency regulation, and emergency backup applications.

3. Photovoltaic Prefabricated Substation (Hua-Type Compact Substation)

Also known as the Hua-type compact substation, this design offers a more compact and lightweight structure compared with traditional European box substations.

Highlights:

  • Approximately 40% smaller footprint than European-style substations

  • High integration and small size

  • Ideal for wind farms, PV power stations, and remote distribution projects

  • Safe, reliable, and easy to maintain

This substation is especially suitable for renewable energy projects requiring high installation density and efficient land utilization.
